I have bought it a few days ago.  First impressions:

• incredible technology, uses any existing mesh and UVmap. far superior to the faceroom in poser
• good support. They promptly answered my e-mail questions
• simple use model
• cheap

• horrible and primitive use interface (am I using the SR1 version? The about screen is not accessible)
• mega buggy software. I may have done around 20 morphs and it crashed on around 10 of them
• it doesn't like iconising
• the control points disappear when the left ear point is entered
• immature, the results are too distorted to be useful without postprocessing
• it really needs a few more sliders to split the overall morph into:
    headshape, eyeshape, ears etc It really needs the facility to cope with a second shot (in profile) when available
• very annoying: you have to enter the control points on imported OBJ meshes EVERY TIME.
  That's half the work per morph and unnecessary
